Abstract

PURPOSE: To make liquid separation by small centrifugal forces possible, and prevent damaging of red blood cells at the separating of serum by putting a thixotropic gel-like separating agent into the bottom of a bottomed blood-collecting tube in the state that a recess is formed in the top surface thereof.
CONSTITUTION: A thixotropic gel-like material 2 is put as a blood separating agent in the bottom part of a blood-collecting tube 1, and a circular cylindrical recess 3 is formed at the center of the top surface thereof by the gel-like material 2. One end of a blood-collecting needle is penetrated into the plug body of the tube 1 and the blood is sampled. If centrifugal separating operation is made after this, the material 2 fluidizes, and the recess 3 expands further largely and so deforms that its one end rises along the tube wall. Further, it moves between a serum layer 4 and a blood cell layer 5 until finally a separating agent 2 layer of roughly uniform thickness is formed between the layer 4 and the layer 5.
